Focus Description:

Put your hand through a metal pipe 25 cm long. After that, push a lit candle into the same place perpendicular to the axis of this pipe (Fig. a). Move the candle "through the hand" and the hand will remain safe and sound.

Focus Candle passing through the hand

Focus secret:

Two holes are made on the surface of the pipe for the free passage of the candle. The holes are located somewhat unusually: they do not go out strictly along the inner diameter, but both are shifted to one side (Fig. b).

Focus Candle passing through the hand

This arrangement of holes allows you to push the candle next to the hand stuck through the pipe and do it in an absolutely safe way.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy.

This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

The world's largest wave power plant will be built 19.12.2022

The Swedish company Eco Wave Power and the Turkish company Oren Ordu Eneas have announced the construction of the world's largest wave power plant. The design capacity of the plant will be 77 MW.

The construction cost will be about $150 million. The installation for converting the energy of sea waves into electricity will consist of a fixed modular array of steel floats, hinged to levers with pistons. The latter will pump the working fluid through an underwater hose line to an onshore generator that produces sustainable energy.

The construction of the project will be carried out in several stages. At the first one, a pilot plant with a capacity of 4 MW will be created in the port of Ordu, and other modules will be added based on the results of the test run and pilot operation.

Despite the great interest in wave energy, this technology has not yet found active application. The Islay LIMPET, the world's first commercial wave device, was installed on the coast of Islay in Scotland and connected to the UK national grid back in 2000. And in 2008, the first experimental wave farm with several generators was opened in Portugal in the Agusadura Wave Park. Its peak power is 2,25 MW.

Despite the low share of wave energy in total production, the US Energy Information Administration estimates the theoretical annual wave potential off the coast of the state at 2,64 trillion kWh, or about 64% of total US energy production in 2021.
